Single-cell RNA sequencing uncovers cellular heterogeneity of granulosa cells and provides a signature for follicular development in chicken

Poultry Science
Functional differentiation of the granulosa cell (GC) layer plays an essential role in follicular development and oocyte maturation in birds. However, despite the importance of GCs, heterogeneity within the granulosa layer across poultry species remains ...
